FREMONT — The man who jumped off a train trestle into Alameda Creek and later died was identified Sunday as 26-year-old Alan Chung, the Alameda County Coroner’s Office said.

Chung, a Fremont resident, was with friends on Saturday who were jumping off the train trestle for fun, police said. Chung jumped into the creek and did not resurface, according to police. Divers discovered his body at about 2:30 p.m.

According to a preliminary investigation, Chung likely drowned. No foul play or suicide was suspected in his death, authorities said.

Otto Warmbier was arrested in January 2016 at the end of a brief tourist visit to North Korea. He had been medically evacuated and was being treated at the University of Cincinnati Medical Center when he died at age 22.
